<b>Description: DBC</b>
<p>The DBC object is the handle for a cursor into a Berkeley DB database.
The handle is not free-threaded.  Cursor handles may be used by multiple
threads, but only serially, that is, the application must serialize
access to the DBC handle.</p>
<p>If the cursor is to be used to perform operations on behalf of a
transaction, the cursor must be opened and closed within the context of
that single transaction.  Once <a href="../api_c/dbc_close.html">DBcursor-&gt;close</a> has been called, the
handle may not be accessed again, regardless of the method's return.</p>
